Cleaning system provides wire glossy finish Advertorial on behalf of Decalub

clean wire before annealing

The GP/PDH-CL system revolutionises the wire cleaning process, benefiting from unique PDH multi-function technology, enabling an automatic control of the crucial process para- meters of pressure/temperature/ viscosity, compound injection speed and thermal stability. In operation, all these parameters communicate in an extremely sensitive and automatic multi-way interaction, providing drawn wire with a bright glossy finish for plating at high-speed, cleaned and polished in-line to a reflective appearance using semi- solid high-viscosity products containing anti-corrosion additives.

Wire cleaning by GP/PDH-CL system

▲

The GP/PDH-CL system is installed in the last draft of a drawing machine to clean drawn wire of lubricant contaminants. It simultaneously performs surface cleaning and polishing, providing a high level of cleanliness of dry drawn wire without the need for aggressive chemicals, and it operates at all practical speeds without limitation. The main reasons for this development have been cost, wire quality and environment factors. The GP/PDH-CL wire cleaning system operates with a wide range of semi-solid lubricating solutions in a continuous “in and out” motion, evacuating lubricant contaminants from the cleaning chamber in an open or closed circuit, completely eliminating wire tunnelling effect and pressure fluctuation, and enabling the highest cleaning speed up to 15 m/s (3,000ft per minute). A light draft of 10% to 15% performs cleaning and polishing in a single run, with completely dry, clean wire leaving the unit. The system is particularly recommended for cleaning wire drawn in severe conditions, with increased heat and burned lubricant tightly bound to the wire surface. The system is compact, easy to install and to use, and it operates at zero energy consumption.

A polyamide 1010, Vestamid Terra DS is produced entirely from monomers obtained from castor oil. Castor oil is obtained from the bean of the castor oil plant, which is used neither as food nor animal feed and whose cultivation does not compete with that of food crops. Vestamid Terra DS moulding compounds are semi-crystalline and distinguished by high mechanical strength as well as resistance to chemicals and stress cracking. They also have high to very high heat deflection temperatures and a low water-absorption capacity, retaining their good mechanical properties such as elongation at break and impact strength, even in high humidity. Areas of application for Vestamid Terra DS cable jacketing include special cables for the automotive industry and underground cables, in which case the bio-polyamide protects against damage caused by gnawing rodents.
